Mix the Patties
In a large bowl, combine ground chicken, cheddar cheese, ranch seasoning, breadcrumbs, egg, garlic powder, and pepper. Mix just until combined.

Shape the Patties
Divide and shape mixture into 4–6 patties. Press a small dent in the center of each to help cook evenly.

Cook the Patties
Pan Method: Heat oil in a skillet over medium. Cook patties 5–6 minutes per side, until golden and internal temp is 165°F.
Grill Method: Grill over medium heat 5–6 minutes per side, with the lid closed.

Toast the Buns (Optional)
Toast buns in a skillet or on the grill with a little butter for extra flavor.
